[ Upstream commit 9c699a8f3b273c62f7b364ff999e873501a1e834 ] The enetc driver uses ifdefs when checking whether CONFIG_FSL_ENETC_PTP_CLOCK is enabled in a number of places. This works if the driver is built-in but fails if the driver is available as a kernel module. Replace the instances of ifdef with use of the IS_ENABLED macro, that will evaluate as true when this feature is built as a kernel module and follows the kernel's coding style.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
